Studying of interrelation of yield of durum spring wheat with vegetative index NDVI of Omsk region steppe zone based on remote sensing

The main way of the world economy development in the XXI century is the alignment of economic development level of most countries. In this case, one of the important factors in this process is the development and implementation of resource-saving technologies. One of the most promising directions of technological progress in agriculture in XXI century becomes the “precision farming” (contour, point), i.e., implementation of any agromeliorative methods in full accordance with the state of the soil and plants in the area at this time. Accumulated experience of using space data since 2005 in OmGAU indicates that the process of the soil decoding based on space data is now becoming a real problem could be solved. In this article new approaches to materials decoding of remote sensing by differential synthesizing of images in different frequency ranges of the Western Siberia steppe zone were firstly published. The correlation between vegetative index NDVI with a yield of spring durum wheat in the Omsk region steppe zone was detected, that will allow to create the cartograms of crops biomass for contour soil fertilization
